Great size. Its medium/small. Not cheap looking which is great. It has space for our phone charger, a drink and a small lamp. (The one in the photo is too big) My fiance put it together within an hour, the instructions were easy to understand. It does not wobble but we do have it on wood. Its not heavy so it does slide around.
